<P>PROBLEM TO BE SOLVED: To provide a sound field reproduction method and a sound field reproduction device using the principle of boundary surface control (BoSC) which reproduces a sound effect in a compact BoSC reproduction room of high quality achieved in a sound space such as a high end listening room. <P>SOLUTION: A sound field reproduction method comprises the steps of: calculating transmission function in sound space p(t) of a predetermined sound space by using a BoSC recording system designed on the basis of the principle of BoSC (step S1); calculating system function h(t) of the BoSC reproduction system designed on the basis of the principle of BoSC by a predetermined arithmetic (step S2); calculating system function with sound effect c(t) by using functions p(t) and h(t) (step S3); and a signal conversion part 22's converting a sound signal s(t) read by a reading part 11 by the system function with sound effect c(t) included in a function inclusion part 21 and outputting it through a BoSC reproduction system 31 positioned in a BoSC reproduction room 30 (step S4). <P>COPYRIGHT: (C)2012,JPO&INPIT |
